To increase the efficiency of a pulley system operating at only 50% efficiency, the best option would be by reducing the friction on the pulleys. Reducing friction can help ensure that more of the input energy is converted into useful work, thereby improving overall efficiency. Adding more pulleys may redistribute the load but typically does not increase efficiency; it can even add to friction if not managed properly.
a pulley system is operating at only 50% efficiency. how could the efficiency be increased?
